If you are familiar with the work of Milton Erickson you will see that he placed a great deal of faith in his client's abilities to mobilize their own internal resources so as to allow them to solve their own problems. Sometimes a lot of people miss this point because instead they focus on his linguistic patterning and his ingenious interventions. When truth be told he had the ability to interact with people in such a cooperative fashion so as to totally melt away their resistance.
To me the ability to create this type of dynamic is of the utmost importance for any would be people helper.
